intervention can improve the learning-memory ability of VD rats, which may be associated with its effects in reducing hippocampal apoptosis by suppressing JNK signaling pathway.OBJECTIVE To observe the effects of electroacupuncture (EA) at "Zusanli" (ST36) on the ultrastructure and mitochondrial dynamics of skeletal muscle tissue in spleen qi deficiency rats, so as to explore the partial action mechanism of EA at ST36 for spleen deficiency syndrome. METHODS Twenty-four male SD rats were randomly divided into 4 groups normal group, model group, ST36 group and non-acupoint group (n＝6 in each group). The model of spleen qi deficiency syndrome was established by improper diet and exhaustive swimming. EA (2 Hz/15 Hz, 0.5 mA) was applied to bilateral ST36 in the ST36 group and non-acupoint in the non-acupoint group for 20 min, once daily for 7 days. The colorimetric method was used to detect the ATP content in skeletal muscle tissue. The ultrastructure changes of skeletal muscle tissue were observed by transmission electron microscopy. The expression levels of optic atrophy 1 (Opa1) and dynamin-related protein 1 (Drp1) mRNA and proteins in the skeletal muscle tissue were determined by flu After the treatment, the expression levels of Opa1 and Drp1 mRNAs and proteins were up-regulated in the ST36 group (P less then 0.05), and the expression of Drp1 protein was up-regulated in the non-acupoint group (P less then 0.05)．. CONCLUSION EA at ST36 can correct the imbalance of mitochondrial fission and fusion in skeletal muscle of rats with spleen qi deficiency, thereby improving the damage of mitochondrial structure and function, and leading to an increase of energy metabolism.OBJECTIVE To investigate the effect of manual acupuncture (MA) and electroacupuncture (EA) on histopathological changes, and levels of oxidative-stress related cytokines and key proteins of the endoplasmic reticulum stress (ERS) pathway in ulcerative colitis (UC) rats, so as to reveal their mechanisms underlying improvement of UC. METHODS Twenty-eight male SD rats were randomly divided into control, model, EA and MA groups (n＝ 7 rats per group). The UC model was established by enema of mixture solution of 5% 2, 4, 6-trinitrobenzene sulfonic acid (TNBS, 100 mg/kg). Rats of the control group received intra-rectal perfusion of normal saline. After modeling, the left "Quchi"(LI11) and "Zusanli"(ST36) were stimulated with EA (2-4 mA，8 Hz/25 Hz) or MA for 20 min, once every other day for consecutive 2 weeks. The rats in the control and model group were just anesthetized and fixed. At the end of experiments, the colon tissue was collected for observing histopathological changes with H．E. staining. The contents of ox levels of SOD, CAT, GSH and T-AOC were all significantly decreased (P less then 0.01), and the content of MDA, and expression levels of p-IκBα， p-p65 and GRP78, p-PERK and p-eIF2α proteins were all significantly increased in the model group relevant to the control group (P less then 0.01). After the treatment, modeling-induced down-regulation of SOD, CAT and GSH in both EA and MA groups, and T-AOC in the EA group, and up-regulation of levels of MDA, p-IκBα， p-p65, GRP78, p-PERK and p-eIF2α in both groups were reversed (P less then 0.01, P less then 0.05). CONCLUSION Both EA and MA treatment can obviously alleviate colonic inflammation in UC rats via inhibiting oxidative stress and ERS.OBJECTIVE To explore the mechanism of electroacupuncture (EA) in accelerating the aggregation of microglia and promoting the remyelination at the location of demyelination. METHODS C57BL/6 mice were randomly divided into 4 groups normal, control, model (LPC) and LPC＋EA. The demyelination model was established by microinjection of Lysolecithin (LPC, 1 µL) into the left corpus callosum. EA (2 Hz/15 Hz, 2－4 mA) was applied to "Baihui"(GV20)and "Zhiyang"(GV9)for 30 min，once daily for 3 days, then, once every other day for 18 days. Immuno-fluorescence staining was used to observe the expression of myelin basic protein (MBP) and Axl tyrosine kinase receptor (Axl), Iba1 and numbers of Olig2-positive oligodendrocytes in the corpus callosum. Western blot was employed to detect the expression of MBP in the corpus callosum, and Oil Red O staining was used to observe changes of number of myelin pieces. RESULTS Following modeling, the expression levels of MBP on day 5 and 10 after modeling were significantly decreased (P myelin regeneration and up-regulate the expression of MBP and Axl of corpus callosum in demyelination mice.Evidence of the continuous rise of novel doping agents and novel doping strategies calls for the development of more accurate multi-target screening methods. Direct multi-target screening approaches are restricted to the targeted substances and their turnover. The development of effective "indirect" screening methods requires a priori a deep understanding of the metabolism of the substance. The biological passport has been demonstrated to be very effective, but it is limited to about 20 indirect parameters. The standard antidoping analytical methods are hence targeted and do not aim directly to identify unknown substances. Also, the detection of doping agents is limited by the excretion of the substance. This study considers metabolomics for the screening of performance enhancing hormone abuse by athletes, based on the following pieces of evidence (1) hormones have a strong influence on human metabolism, changing several parameters in many tissues, organs, and bio-fluids; (2) metabolomics has been demonstrated to be a very accurate tool to depict the metabolic status of several organisms, tissues, and for several human diseases, including hormone deficiencies; (3) metabolomics has been demonstrated to be able to distinguish hormone-treated animals from controls in many species, without the need for a priori knowledge of the metabolism for the specific substance. The literature shows that metabolomics could be an appropriate tool to detect hormone abuse, keeping in mind the strength and the limitation of such an approach. © 2020 John Wiley & Sons, Ltd.Febrile neutropenia (FN) is a critical complication of chemotherapy associated with increased in-hospital mortality. However, associations with increased mortality and intensive care unit (ICU) admissions during longer follow-up are not established. Patients treated with standard first-line chemotherapy for solid cancers at Rigshospitalet, Denmark in 2010-2016 were included. Incidence rate ratios (IRR) of all-cause, infectious and cardiovascular mortality, and ICU admissions after FN were analyzed by Poisson regression. Risk factors at the time of FN were analyzed in the subpopulation of patients with FN; all-cause mortality was further stratified by the time periods 0-30, 31-365, and 366+ days after FN. We included 9018 patients with gastric (14.4%) and breast (13.1%) cancer being the most common, 51.2% had locally advanced or disseminated disease and the patients had a median Charlson Comorbidity Index score of 0 (interquartile range, 0-0). During follow-up, 845 (9.4%) experienced FN and 4483 (49.7%) died during 18 775 person-years of follow-up. After adjustment, FN was associated with increased risk of all-cause mortality, infectious mortality, and ICU admissions with IRRs of 1.39 (95% CI, 1.24-1.56), 1.94 (95% CI, 1.43-2.62), and 2.28 (95% CI, 1.60-3.24). Among those with FN, having a positive blood culture and low lymphocytes were associated with excess risk of death and ICU admissions (predominantly the first 30 days after FN), while elevated C-reactive protein and low hemoglobin predicted mortality the first year after FN. The risk of death varied according to the time since FN; adjusted IRR per additional risk factor present for the time periods 0-30, 31-365, and 366+ days after FN were 2.00 (95% CI, 1.45-2.75), 1.36 (95% CI, 1.17-1.57), and 1.17 (95% CI, 0.98-1.41). FN was associated with increased mortality and risk of ICU admissions. An objectively identifiable subgroup of patients among those with FN carried this excess risk. © 2020 The Authors.

METHODS Using data from 343 participants of the Intensive Diet and Exercise for Arthritis (IDEA) trial, we applied 24 machine-learning models to develop individualized treatment rules on seven outcomes SF-36 physical component score, weight loss, WOMAC pain/function/stiffness scores, compressive force, and IL-6. The optimal model was selected based on jackknife value function estimates that indicate improvement in the outcome(s) if future participants follow the estimated decision rule compared against the optimal single, fixed treatment model. RESULTS Multiple outcome random forest was the optimal model for the WOMAC outcomes. For the other outcomes, list-based models were optimal. For example, the estimated optimal decision rule for weight loss assigned the D+E intervention to participants with baseline weight not exceeding 109.35 kg and waist circumference above 90.25 cm, and assigned D to all other participants except those with history of a heart attack. If applied to future participants, the optimal rule for weight loss is estimated to increase average weight loss to 11.2 kg at 18 months, contrasted with 9.8 kg if all received D+E (p = 0.01). CONCLUSIONS The precision medicine models supported the overall findings from IDEA that the D+E intervention was optimal for most participants, but there was evidence that a subgroup of participants would likely benefit more from diet alone for two outcomes. https://www.selleckchem.com/products/gsk1120212-jtp-74057.html This article is protected by copyright.

METHODS Data from 108 participants (78 women; 48.7 [SD 11.6] years; BMI 31.4 [SD 4.6] kg/m2 ), randomly assigned to either the moderate-dose exercise group (8 kcal/kg of body weight per week) or the high-dose exercise group (20 kcal/kg of body weight per week) of the Examination of Mechanisms of Exercise-induced Weight Compensation (E-MECHANIC) trial, were analyzed. Moderate-to-vigorous PA (MVPA), steps per day, and PA energy expenditure (PAEE) were measured with SenseWear armbands (BodyMedia, Pittsburgh, Pennsylvania), and total activity energy expenditure and EI were estimated with doubly labeled water, all over 2 weeks, before and toward the end of the intervention. Multiple linear regression models, adjusted for sex, exercise group, and baseline value of the outcome, were used. RESULTS Baseline habitual MVPA levels predicted weight change (β = -0.275; P = 0.020), weight compensation (β = -0.238; P = 0.043), and change in EI (β = -0.318; P = 0.001). Associations between baseline PAEE and outcomes were comparable, whereas steps per day and, importantly, total activity energy expenditure (via doubly labeled water) did not significantly predict change in weight-related outcomes. CONCLUSIONS While acknowledging substantial variability in the data, on average, lower baseline habitual MVPA and PAEE levels were associated with less weight loss from exercise, higher compensation, and increased EI. © 2020 The Obesity Society.
